Alcoa and Maaden teamed up in 2009 to build the world’s largest fully integrated aluminium complex in Ras Az Zawr, on the Gulf coast, fast becoming Saudi Arabia’s mining cluster.

Maaden signed a letter of intent with Samsung which involves engineering, procurement and construction of a rolling mill as well as testing the plant, Maaden said in a statement on the bourse website on Wednesday.

The project would take 32 months to complete, it added.

The statement named the company only as Samsung but an industry source said the deal was signed with Samsung Engineering.

The rolling mill would produce 380,000 tonnes annually of aluminium sheets, it said. When Maaden and Alcoa first announced the project they said the mill would have a capacity of up to 460,000 tonnes. (Reporting by Reem Shamseddine; Editing by Hans Peters)
